Plymouth boot screen bug

Can I remove Plymouth without consequences? On my system, from behind it, periodically hangs during the boot of the system and shutdown. I edited Mkinitcpio Hooks, removing the Plymouth and replacing the Plymouth-Encrypt on Encrypt, during the download system, the problem disappeared, but during the shutdown 50/50, the system hangs. Thank you in advance for the answer.

What if you just remove splash from boot parameters?
I don't know if this is enough, but I think you could try...

I tried it. No effect ...

I'm fairly sure of this (I've never dealt with the encrypt stuff) as I am a disliker of Plymouth.
Step one is to uninstall plymouth.
Then disable sddm-plymouth - from a console, not a terminal app. Stopping sddm will also halt your desktop.
systemctl stop sddm-plymouth.service
systemctl disable sddm-plymouth.service
and enable sddm,
systemctl enable sddm.service
and on reboot plymouth should be gone.

You may want to remove 'quiet' from your kernel parameters (if it's there).
